I really can´t see any problems with a full. I am 5´11 and my bed is 35 inches. When I share the bed with someone, it´s still plenty room. Three is getting cramped, but still works. Then again. I´m in college. Anyways, if I´m bigger than you, and can fit three in a bed smaller than yours, there is no reason to opt for an even bigger one. That just means you have to pick skinnier chicks. It´s a lifesaver really. If she´s to fat to fit, she isn´t staying the night.

I have a queen sized bed, but I used to sleep in a full sized bed and don't see much difference. If you'd like extra space in your room, why not opt for a full sized bed instead of a Queen? You'll still have plenty of space to strech out.

I'm 6'6" and a queen works well enough for me. Sometimes I dream about a California king, but don't believe the bed would fit well in my rental pad. Plan to stick with a queen till I get married and having a little more bed space would make sense.
